Definitions

  • This invention concerns steering compartment equipment for boats with an inclinable and height adjustable wheel, normally called a “Tilt wheel.”
  • this steering equipment features essentially a mobile support for the wheel shaft, supported by stirrups, the inclination of the mobile support and of the wheel shaft being blocked or released by a pawl meshing with a sector gear, features a universal joint connecting the mobile shaft with the fixed shaft of the steering, equipment and features protections, gaskets and seals to protect the equipment from splashes, waves and bad weather.
  • a second drawback is due to the fact that the control shaft of the steering equipment, where it crosses the dashboard, is not adequately protected against leakage and splashes.
  • Another drawback is caused by the fact that the mechanical strength of the universal joint located between the fixed control shaft of the steering equipment and the mobile wheel shaft now causes trouble and jamming, because of the sometimes even strong stresses and strains to which this universal joint is exposed and of the corrosive environment in which it is operating, especially during sometimes long tie-up periods.
  • the external protection of the tilting device consists of three components, i.e. a first fixed covering protecting the parts of the device secured to the dashboard, a second mobile covering protecting the mobile part of the device, linked up to the wheel and a third component, i.e. a toroid or band shaped sealing ring connecting in an articulated way the above first and second protections.
  • the band shaped sealing ring has a particular configuration, which permits to bend outwards the edge facing the second mobile covering, on which this edge, after insertion, is fitted in normal sealing position.
  • the steering equipment is installed by mounting this equipment on the dashboard and then fitting the first fixed covering, already provided with the outwards folded seal; the second mobile covering is then positioned, so that it penetrates the band shaped sealing ring which is finally elastically counter bent so that it is normally resting on the lower edge of this second mobile protection.
  • the second protection is mobile with respect to the first protection and is capable to follow the movements of the tilt wheel while providing an excellent seal against water seepage in any and all tilt positions of the wheel.
  • an O-ring is sealing off the opening through which the control shaft of the steering equipment crosses the dashboard; this O-ring, together with the flange shaped packing placed between the dashboard and the fastening plate of the tilt wheel, further improves sealing conditions and makes the system, especially the dashboard, waterproof.
  • the universal joint moving the steering equipment by means of the tilt wheel, is provided with four identical stirrups, which can therefore be indifferently assembled according to needs, and with a cross journal featuring a central body formed by a square parallelepipedon with chamfered edges so as to permit the maximum reciprocal inclination of the fixed and mobile shaft, without interference with the stirrups, while a steel bar with oversized cross section may be used at the same tire as cardan shaft.
  • Four bushes with flanges in suitable material are provided on the head of the cross shafts, to prevent the steel of the cross journal from gripping on the aluminium stirrups when the equipment is not used for some time.
  • the steering equipment with tilt wheel is usually mounted on the dashboard with a flange featuring an inclined base, to allow for symmetrical installation with 180° rotation, with a pawl to block and release the tilt of the wheel in upper or lower position.
  • FIG. 1 shows a perspective top view of the exploded equipment forming the tilt wheel
  • FIG. 2 shows a perspective view from below of the compacted equipment shown in FIG. 1 .
  • FIGS. 3, 4 , 5 and 6 show a vertical section of a deformation sequence of the band shaped sealing ring fitted between the first fixed and the second mobile protection.
  • FIG. 7 shows a perspective exploded view of the universal joint, mechanically connecting the fixed shaft of the steering gear to the mobile wheel shaft.
  • 1 shows the wheel shaft connected to a support, adjustable by means of supporting stirrups, the tilt of this adjustable support and of the wheel shaft 1 being blocked or released by a tooth meshing with a sector gear.
  • a universal joint 3 is mounted between the mobile wheel shaft 1 and the fixed shaft 2 of the steering equipment, to provide for offset rotation of the two shafts 1 , 2 .
  • a base plate 4 is located in the lower zone of the equipment, this base plate 4 being secured, by means of a flanged gasket 5 , to the dashboard of the boat.
  • this invention has the aim to improve the external protection of the equipment against splashes and water seepage and, according to this invention, this protection is provided by three components, i.e. by a first fixed annular covering 6 to protect the parts of the tilt wheel fastened to the dashboard, a second annular mobile covering 7 , to protect the upper mobile part of the device and an intermediate toroid shaped seal 8 , located between the aforesaid first and second covering 6 , 7 .
  • the first covering 6 and the second covering 7 are respectively mounted on the fixed and mobile parts of the equipment by means of fastening devices, such as bolts.
  • the toroid shaped seal 8 as illustrated in FIG. 3 features a lower internal circular recess 9 which is useful to fit the seal 8 on the upper zone of the fixed covering 6 by means of the matching peripheral shaping 10 .
  • This band shaped seal 8 when in rest position, features at its upper end an inwards bent shaping 11 , so that this shaping 11 will rest on the outer surface of the lower portion of the mobile covering 7 .
  • the protecting seal 8 is thus fixed onto the fixed covering 6 and is resting on the mobile covering 7 , providing an efficient overall seal against splashes and water seepage while leaving the mobile covering 7 freely to follow the movements of the tilt wheel.
  • a recess 12 is preferably provided in the internal zone of the flanged seal 8 so as to form a weaker circular zone inside the body of the seal, to permit a simpler and easier elastic outwards bending of the upper shaping 11 as illustrated in its sequenced phases in FIGS. 4, 5 , and 6 .
  • the second mobile upper covering 7 can be easily inserted in the flanged seal 8 which would have prevented its entering if bent inwards. After assembly of the second mobile covering 7 , the normal curvature position of the flange 8 is elastically restored.
  • a drop-tight O-ring 13 is fitted on the fixed gear shaft 2 passing through the dashboard, at its breakthrough level.
  • This O-ring 13 together with the flanged gasket 5 inserted between the base plate 4 and the dashboard, considerably increases the possibility to protect the equipment and the dashboard from water infiltration and splashes.
  • the universal joint 3 acting as a mechanical sequence between the mobile shaft 1 of the tilt wheel and the fixed shaft 2 of the steering equipment, features four identical stirrups 14 which may be positioned anywhere inside the universal joint and also features a cross journal 15 provided with articulated shafts 16 , 17 , the ends of which, penetrating in the various stirrups 14 , are protected by preferably flanged ferrules 18 in suitable material, which ferrules will prevent the steel of the cross journal from gripping on the aluminium stirrups when the system is not used for some time.
  • the cross journal 15 has the form of a square parallelepipedon with chamfered edges 19 and these chamfers 19 make it possible to obtain the maximum inclination between the fixed shaft 2 and the mobile shaft 1 without interfering with the stirrups 14 .
  • the base plate 4 to be mounter on the dashboard has a slanting form, with the possibility of an 180° opposed symmetrical installation, the grip and release pawl for inclination of the tilt wheel being located at the top or bottom.
